The mountain biker's ebike

Living in uncharted territory, the Relay is a lightweight, mid-power ebike here for all your rides, battery or human powered. From square one the relay was built with modularity in mind. starting with a frame that accommodates 160 or l70mm travel from and rear, as well as dual 29 or mixed wheels, this bike is ready for any trail you point it down. At the core of this chariot is the Fazua Ride 60 system that provides 60Nm of torque to get you pup the hill, with a 430Wh battery to keep you going for miles on end.

We have always wanted a bike that could provide both an ebike and a human powered experience in one chassis, and this is it. This system is light, efficient and quiet. Providing a more intuitive and natural feel on trail than many expect from a powered ride. The Relay is here to meet all of your mountain biking needs.

Two bikes in one

The Relay can be ridden as an ebike or a non-powered bike by simple removing the battery. The drive unit has such minimal drag that when your ride it powered off and without the battery, you'll quickly forget you still have a motor in your frame. During our development process we tested it without the battery and found very little difference even with the small amount of added weight from the motor that stays low and centred. This aspect of the Relay opens up avenues that many haven't addressed before. It fills the desires of a rider looking for the ebike experience, while also allowing riders to remove the battery to pedal with friends not on ebikes, shuttle, ride the bike part or ride in areas not accessible to ebikes. You can quickly open the tool free battery door, remove the battery from the frame and let your legs do the rest. We think many riders are currently faced with the decision to purchase either an ebike or a non-powered bike, not both and the Relay will be their answer.

Fazua Ride60 motor

The Fazua Ride60 system has 60Nm or torque and 450W peak power with virtually no drag. This creates a very efficient system that punches far above what its numbers would suggest. With the smooth power delivery and extremely quiet motor, the Relay is one of the most intuitive and natural feeling ebikes pushing the ride experience closer to that of a non-powered bike.

Fazua Energy 430Wh battery

The 430Wh battery is easily swappable and provides range similar to what we are finding on larger battery, higher power ebikes. An external range extender will be available in the future.

Fazua ring controller

The simple and ergonomic ring controller has three ways of movement, up, down and inward. Pushing up increases the power level, while pushing inward will activate walk mode. Additionally, holing the controller up will activate boost mode, giving you peak power output for roughly ten seconds of boost.


The simple interface on the top tube consists of 5 led lights to give you an indication of power mode, battery life and a connection port for your phone or other device. Out of the box the relay has three power modes, breeze, river and rocket. breeze mode provides enough assistance to well overcome the additional weight of the bike and is very usable in many situations where you are not trying to go much faster than normal biking pace. River mode is pre-set to match the amount of energy you are delivering to the pedals, providing a natural feel that can deliver across the range of power. rocket mode provides full system power to help tackle the steepest and most challenging terrain.
